Ship Motion Generator Upgrade Study.

Abstract

A study was undertaken to determine the specifications for a piston that would bring the Ship Motion Generator back to the original heave displacement of + or - 11 feet, reduce piston whip, decrease the lower overtravel buffer deceleration and retain the 17 ft. per second maximum velocity. Recommendations were made to modify the heave drive system and tower structure. (Author)
